They are quieter, yes. Nuclear subs aren't all that stealthy because the reactor is constantly making noise. They are designed to stay submerged for long periods of time, not engage other subs at ranges where the noise gives them a disadvantage. The hope is that they can't be found in the vast ocean, or at least not consistently enough to negate the threat of nuclear retaliation.
Battery electric propulsion can't be beat for stealth.
